MMRF1011HR5

Overview

The MMRF1011HR5 is a pulse lateral N-channel RF power MOSFET manufactured by NXP Semiconductors. It operates within the L-band frequency range of 1200 to 1400 MHz, delivering a peak output power of 330 W at a drain voltage of 50 V. The device is engineered for high-efficiency pulse applications with duty cycles ranging from 1% to 12%. Constructed using silicon technology, it utilizes a reel packaging format and is identified as an archived product no longer in active manufacturing.

Feature Summary

• Designed specifically for high-power pulse operation in the L-band spectrum
• Utilizes lateral N-channel RF power MOSFET architecture for robust performance
• Capable of sustaining 330 W peak output under specified pulsed conditions

Applications

• L-Band radar systems requiring high peak power pulses
• Pulse amplifier stages operating between 1200 and 1400 MHz
• Military and aerospace communication equipment utilizing L-band frequencies

Procurement Notes

This component is officially classified as archived and no longer manufactured by NXP Semiconductors. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory channels. Buyers must confirm end-of-life status and potential supply constraints before initiating procurement processes for this specific part number.

Selection Notes

Engineers selecting this device should account for its discontinued status when designing new products. The MMRF1011HR5 is suitable only for maintenance or legacy system repairs where original specifications are mandatory. Alternative solutions should be evaluated if long-term supply assurance is required for new production runs.

Part Context

The MMRF1011HR5 belongs to NXP's portfolio of L-band RF power transistors designed for demanding pulse applications. It shares architectural similarities with other devices in the MMRF10xx series but is distinct in its specific frequency coverage and power handling capabilities. The suffix HR5 indicates the reel packaging configuration used for tape-and-reel delivery.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the device is archived, direct replacements may require functional equivalents from other manufacturers or updated NXP components with similar electrical characteristics.
